The Invisible Prompt Injection Hack & AI’s "Fire Triangle"

Is your organization treating AI agents like unvetted employees? With 98% of organizations harboring unsanctioned AI tools, the risk of data exfiltration and prompt injection is higher than ever . In this episode, Ashish sits down with Rob Juncker, Chief Product Officer at Mimecast. Rob challenges the traditional security narrative to build defenses, advocating instead for a "remediate first, alert second" approach to scale the modern SOC . He shares a terrifying real-world example of an invisible prompt injection attack: a benign-looking email using white text on a white background that instructed the user's AI assistant to secretly download and exfiltrate their entire private inbox without logging the action . Rob also introduces the "Fire Triangle" of AI security -Fuel (private data), Oxygen (exfiltration paths), and Heat (threats/prompt injections) and explains how removing just one element neutralizes the danger . If you want to understand how to build a Human Risk Exposure program that scales alongside AI, you will find this conversation interesting.
